To me, the Spiderman series, and most superhero franchises, are played out. Given the narrow confines inherent to the genre there’s just no place for them to go that you haven’t essentially already seen many times before. There has to be a super villian. Somehow the super villian threatens the world, country, town, etc. etc. Super hero is the only hope to save the day. By the halfway mark in the movie the villian has somehow gotten the upper hand and things look bleak. Somehow, though, superhero overcomes the obstacles and in the last 20 minutes of the film hero arrives in the nick of time to win the 15 minute final boss battle scene. Hooray. Every move is some variation of that and I’ve just gotten bored with them. Granted they still do big box office and will continue to be made as long as they do. More power to the studios in that respect - long live capitalism and the people it employs. And if you like them I’m certainly not criticising you - nobody has to account to anyone for the movies they enjoy. Long live freedom. But for me personally the superhero movie just got to be a bore.
What you say could also be said of the comic book series themselves. Except the story arcs are not as formula of Disney-Marvel’s movies (who delight in telling boring origin stories, no one gave damn James Bond or each of his villains came to be).
Rather than significantly adapting one of the highlighted stories in the character franchises, they stick to a basic melodrama. The first film of the first Spider-Man franchise did leverage heavily off of several recurring plot lines and specific (although altered) storylines.
Getting bored/tired of seeing these giant flying fortresses threatening a city in Avengers, Capt. America, Guardians of the Galaxy, etc.
And the whole mutants=homosexuals (justice for all) plotlines of the X-Men series are a bit tiresome (gay director with an agenda). X-Men came to be a “big” title in the 80s because of other plotlines (including Dark Phoenix, not even a player in this franchise). The discrimination subplot was present in Lee’s original series (which began when segregation was still a thing; it’s been altered into “But mom, I was born this way!”).
There are other villains for Batman to fight than Joker as well.
Hey, you gave away the ending of virtually every movie ever made.
